Title: Trailer brake control valves
IPC: B60T15/24
Filed: 1974-06-07
Abstract: 1465056 Trailer brake control valve CLAYTON DEWANDRE CO Ltd 7 June 1974 [8 June 1973] 27397/73 Heading F2F A trailer brake control valve is provided for use in tractor-trailer braking systems of the kind in which the tractor braking system incorporates spring brake units as secondary braking means. The valve comprises two spring connected pistons 3, 10 each responsive, in use, to a different service line pressure and the piston 3 carries a valve actuating member 6. A valve element 19 co-operates with a seating structure 17, 18 and is adapted on displacement from its seat by the actuating member 6, in use, to disconnect the trailer service brake line from an exhaust connection 20 and connect it to a supply of pressure fluid as through ports 23, 27. A further piston 26 is responsive to pressure, in use, in the tractor spring brake control line and when pressure in this line is reduced allows the displacement of the valve seating structure thereby to effect actuation of the valve to pressurize the trailer service brake line. The displacement of the valve seating structure is effected by pressure acting upon a piston area 17a integral with the seating structure and loading the seating structure in a direction opposite to the loading on the further piston 26. A further piston 7 is interposed between pistons 3 and 10. The space between the pistons 7 and 10 may be vented to atmosphere or may, in use, be connected to a controlling pressure from a separate trailer control valve. Provision may be made for replacing the piston 26 by pistons of different effective areas for matching the control valve with tractor trailer braking systems having different working pressures.

Title: Improvements in or relating to electrically operated control systems
Inventor: GROUT JOHN ARTHUR MUMFORD
IPC: G05B11/01
Filed: 1963-07-11
Abstract: 1,092,105. Automatic control. GEORGE KENT Ltd. July 10, 1964 [July 11, 1963], No.27575/63. Heading G3R. A process controller comprises a high-gain, high-impedance D. C. amplifier having an input voltage or current representing the deviation from a set value of a condition, then being a feedback circuit including a single capacitance providing a phase lag, and a means connected to the output of the amplifier providing an analogue or pulsed output operating a regulator so as to tend to reduce the input deviation to zero, wherein upon the means actuating the regulator, current is supplied at a controlled rate to the feedback capacitance so that the output to the regulator is zero when the deviation is zero and represents the time-derivative of the required regulator position. As shown, Fig.1, an input current io, representing deviation from a set point, is fed through a proportional and derivative circuit 12 to an high gain, high impedance D. C. transistor amplifier 13, comprising a transistor input chopper, an A. C. amplifier, a transistor demodulator and a feedback integrator to smooth the demodulated signal. The amplifier output is fed to transistorized trigger devices 19, 20, having a deadband about the zero input point. The devices 19, 20 actuate relays 22, 23, contacts 22a, 23a of which control the energization of winding 24, 25 of a motor 26 operating a regulator, not shown, such as a gas supply valve of a gas-fired furnace to maintain the measured furnace temperature at a desired value. Depending upon which relay is actuated a contact 22b, 23b is closed to connect a negative or positive source to a resistance RC, whereby a feedback capacitor C1 is charged. The change of voltage on the capacitor C1 causes a backing-off current through a resistance Rf which reduces the amplifier input to a value at which the trigger is switched off. The time for the trigger to be reset is adjusted by resistor Rc and occurs if the deviation is sufficient to exceed the trigger threshold. The trigger thus operating periodically until the deviation is reduced substantially to zero. The recurrence frequency is dependent on the rate of discharge of capacitance C1 through a resistance R T . In a modification, Fig.4, not shown, the trigger devices and relays are replaced by a reversible D. C. motor, the resistor Rc being supplied by the amplifier output; the resistor R T  being no longer necessary. In an alternative arrangement, Fig. 5, the output across the resistance Rc and capacitance C 1  feeds an analogue to pulse frequency converter comprising a buffer amplifier 34, a voltage-frequency converter 35 and a reversible counter 36. The converter 35 provides a drive in one direction only, the signal to the counter being taken from a switching signal lead to a transistor T6 from a voltage detector 41 responsive to the voltage on a condenser C2, determined by a reversing switch D1-D4 and a transistor T5 which is controlled by the transistor T6.

Title: Improvements relating to an automatic stopping device for a staple fibre cutter
IPC: C07D333/22
Filed: 1952-11-04
Abstract: 715,258. Stop motion for staple fibre cutters. CHEMSTRAND CORPORATION. Nov. 4, 1952 [Nov. 14, 1951], No. 27749/52. Classes 120(2) and 120(3) A stopping device for a staple fibre cutter comprising a cutter, e.g: a rotary disc cutter, and feeding means for feeding a strand to the cutter, e.g. rotatably mounted godets, has a device connected to the cutter for removing staple fibres therefrom, a device mounted in the removing device for collecting staple fibres, at least one strand operated switch adjacent the feeding means, a brake attached to the feeding means, an electromagnet attached to the removing device adjacent the collecting device, and electrical conductors connecting the switch, the feeding means, the brake and the electromagnet. As shown a strand 3 is led under a lever 4 of a drop switch 5 then around feed godets 6 and 7 driven by a motor 9 and on to a rotary cutter 10. A conduit 11 is positioned above the cutter 10 and the knife blade 12 is positioned therein. Cut staple fibres 3a pass upwardly through conduit 11 and a compressed air line 13 may be positioned in the conduit. Pivotally mounted in conduit 11 is a screen 14 attached to which and extending at right angles thereto is a plate like member 15 having a block 16 attached to it. An electromagnet 18 is attached to the conduit 11 by means of a bracket 17 and when the apparatus is in operation the member 15 is swung up so that the block 16 contacts the energized electromagnet 18 and the screen 14 is thus held in the position shown in full lines. An electromagnet brake 21 is fastened on the shaft of the motor 9 and this brake, the motor 9 and the electromagnet 18 are connected in parallel to a source of electric power and the switch 5 is connected in series with them. The arrangement is such that should the strand 3 break or become excessively slack the switch 5 opens, thus causing the brake 21 to operate and stop the motor 9, and the member 15 to be released by the electromagnet 18. The latter action permits the screen 14 to swing into the dotted line position to collect any fibres leaving the cutter which are of irregular lengths.
